Terry, congratulations on your pending purchase. Your coach is 5 years old, even though it only has 10K miles. A complete change of all fluids and filters would be prudent. Oil, fuel filters, transmission oil change and filters w/ TranSynd, air cleaner, air brake system air filters, rear end (use synthetic), coolant. Don't forget to put a full fresh service on the generator.
With the above done, you now have a baseline to start the appropriate time intervals for the appropriate systems.
Good luck with your pending purchase.
